Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

| Description | This is a part of collaborative project. The task at City is to develop methodology for generating multiple directional wave groups propagating in different directions and methodology for modelling interaction between wave impact and response of floating bodies. The main achievements include: 1) Develop a method for modelling 3D nonlinear directional waves by improving the Spectral Boundary Integral Method for simulating nonlinear water waves. 2) Develop a hybrid method for modelling 2D Non-breaking and Breaking Waves. This is first paper to present a hybrid method coupling a meshless method based on the Navier Stokes (NS) equations, with a finite element method (FEM) based on the fully nonlinear potential flow theory (FNPT) in order to efficiently simulate the violent waves and their interaction with marine structures. 3) Numerical and Experimental Studies of Interaction between FPSO and Focusing Waves and hydrodynamics in gap between two Structures. 3) |
| Exploitation Route | The new 3D method for modelling 3D nonlinear directional waves have been used for developing another method, called Enhanced Spectral Boundary Integral (ESBI) method for modelling fully nonlinear wave-current interactions, which is more efficient to model directional waves in a relative large domain. The idea of hybrid method developed in this project has been adopted by other researchers and have been extended to solve 3D wave-structure interaction problems. |

| Description | Not yet now but we are working together with Livermore Software Technology Corporation to combine our QALE-FEM code with their commercial software to deal with interaction between waves and structures. The above was stopped. We are now working on combining QALE-FEM with OpenFOAM and will consider to release a open source code. The method developed in this project have been adopted and extended by other researchers and projects. |
